A letter that goes with the book
Tuesday
The book is thirteen weeks. The year after the work ends is longer than that.
Tuesday is a short letter, once a month, for that first year. Each one picks up an old story from Scripture, the way the book does, and leaves you with one thing to try before the next one comes. It's named for the first Tuesday with nothing on the calendar.
You don't have to have read the book, and you don't have to believe any of it. Like the book, it doesn't assume.
